Welt cord and stitch pattern for a back rest for a chair



FIG. 1 is a perspective view showing the top, left side and front of a back rest for a chair having the welt cord and stitch pattern which form my new design, the broken lines showing other parts of the chair being for illustrative purposes only and forming no part of my design;

FIG. 2 is an enlarged detail of the welt cord and stitch pattern on the backrest taken from the detail outlined in FIG. 1; and,

FIG. 3 is a cross-section taken along lines 3—3 of FIG. 2.

The short broken lines shown in FIGS. 1 and 2 are understood to represent stitching and the long dashed lines shown on the side backrest, armrests, seat and base in FIGS. 1 and 3 are for illustrative purposes and form no part of the claimed design. 

The ornamental design for a welt cord and stitch pattern for back rest for a chair, as shown and described.
